What is a Trojan?

What is a Trojan Horse? Borrowed from the story of the wooden horse used to trick the defenders of Troy into sneaking soldiers into their city, a Trojan Horse hides malware in what appears to be a normal file. There are a wide variety of Trojan viruses on the Internet landscape that can perform an array of tasks. Most Trojans are typically aimed at taking control of a user’s computer, stealing data and inserting more malware on to a victim’s computer.

Trojanized apps

Trojans aren’t just problems for laptop and desktop machines. They can also impact your mobile devices as well. Generally speaking, a Trojan comes attached to what looks like a legitimate program, however, it is actually a fake version of the app, loaded up with malware. These cybercriminals will usually place them on unofficial and pirate app markets for unsuspecting users to download. In addition to the threats mentioned above, these apps can also steal information from your device, and generate revenue by sending premium SMS texts.

How to Stay Protected:

Computer security must begin with an Internet security suite. Run periodic diagnostic scans with your software. You can set it up so the program runs scans automatically during regular intervals.

Update your operating system’s software as soon as the updates are available from the software company. These groups tend to exploit security holes in outdated software programs. In addition to operating system updates, you should also check for updates on other software that you use on your computer as well.

Don’t visit unsafe websites. Most Internet security suites include a component alerting you that the site you’re about to visit is unsafe.
